The purpose of this paper is to develop a methodology which can be used to set X-factor under price cap schemes, when the number of observations is limited. We firstly apply a panel index approach across Water and Sewerage companies (WaSCs) over time to decompose unit-specific index number based...

The purpose of this paper is the evaluation of various profit drivers such as price changes, productivity changes and quality levels on the financial performance of the Water and Sewerage Companies (WaSCs) over time in the case when the number of observations is limited. We thereby follow...

In this study we apply an index number approach to allow for cross sectional comparisons of relative profitability, productivity and price performance of the regulated Water and Sewerage companies (WaSCs) in England and Wales during the years 1991-2008. In order to better analyse the impact of...

This paper investigates the determinants of profit change over the period 1991-2008 for the Water and Sewerage Companies (WaSCs) in the English and Welsh water and sewerage industry. We firstly apply an input oriented profit decomposition approach following the approach of De Witte & Saal...

Cost functions are estimated, using random effects and stochastic frontier methods, for English higher education institutions. The article advances on existing literature by employing finer disaggregation by subject, institution type and location, and by introducing consideration of quality...

As student numbers in higher education in the UK have expanded during recent years, it has become increasingly important to understand its cost structure. This study applies Data Envelopment Analysis (DEA) to higher education institutions in England to assess their cost structure, efficiency and...
